Specification of Letters. Patent.

Patented Nov. 4, 1919.

To all whom it may concern Be it known that 1, CHARLES E. MORRIS, a citizen of the United States, residing at Leavenworth, in the county of Leavenworth and State of Kansas, have invented a certain new and useful Improvement in Centrifugal Guns, of which the following is a specification.

The object of my invention is to provide a novel gun which will throw a projectile accurately and with great force, which will be automatically charged, which may be readily controlled by an operator located at a distance from the gun, and in which the angle of fire may be adjusted at the will of the operator.

My invention provides further novel means for collecting the projectiles which have been discharged from the gun and returning them to the magazine of the gun. My invention provides further a novel escapement mechanism controllable at a distance by the operator for releasing the projectiles one by one from the magazine for discharge into the barrel of the gun.

My invention provides still further a novel barrel arranged to receive the projectiles from the magazine and any time during the revolution of the barrel.

My invention provides still further novel detent means controllable by the operator for holding a projectile in the barrel until such time as the gun is to be fired.

My invention also provides novel means for reducing the speed of the projectile through the barrel and up to the point of its detention in. the barrel where it remains until released by operation of the detent mechanism.

My invention provides still further novel means for adjustably controlling the time of discharge of the projectile relatively to the position of the gun in its revolution.

Other novel features of my invention are hereinafter fully described and claimed.

Similar reference characters designate similar parts in the different views.

1 designates a-supporting frame of any desired form andconstruction and which has rotatably mounted in it a transverse horizontal shaft 2, which is driven by any suitable means, such as an electric motor 3 having pulley 4 secured to an armature shaft 5, a belt 6 being mounted on the pulley 4 and on a pulley 7, the latter being secured rigidly to the rotary shaft 2.

Secured to and revoluble with the shaft is a barrel, comprising, in the preferred form of my invention, shown in Figs. 1., 2, 7 and 8, a substantially circular receiving chamber 8, which is centrally secured rigidly to the shaft 2, and which communicates peripherally with a radial tubular portion 9, into which the projectiles which may be balls 10, are consecutively discharged from the chamber 8.

As shown in Fig. 8, one end of the chamher 8 is normally closed by a stationary cover plate 11 which is rigidly secured to the frame 1 and which has an opening 12 which connects the chamber 8. with a U-shaped tubular magazine 13, the upper end of which is open and so disposed as to receive projectiles delivered therein by a conveyor comprising an endless inclined belt 14 having a series of transverse blades 15, Figs. 1 and 2, adapted to engage and carry upwardly the projectile balls 10, as the latter are delivered by an inclined chute 16 to a point at the lower end of said chute and in the path of the blades 15.

The chute 16 is disposed transversely to the line of fire of the barrel 9, and the ground 17 is inclined toward and at its lowermost portion is flush with the forward side of the chute 16, so that projectiles falling upon said ground 17 will roll into the chute 16, and in rolling down the chute will reach the point where they will be consecutively engaged by the blades 15 of the conveyer and by said blades delivered into the upper end of the magazine 13 over a semi-circular plate 18, Fig. 2, having its open side laterally disposed so that the projectiles 10, when the magazine 13 is filled, will be discharged laterally at the outer side of the magazine.

The belt 1 1 is mounted on two pulleys 19 and 20 which are rotatably mounted on a frame work 21, by means of two transverse shafts 22 and 23 respectively.

The shafts 22 and 2.3 are rotatably mounted respectively in the upper and lower ends of the frame work 21, which frame work is supported by the frame' 1.

Secured to the shaft 23 is a pulley 24 connected by a belt 25 with a pulley 26 secured to the shaft 2. By this means, the conveyor is driven when the shaft 2 is rotated.

Releasable detent means is provided in the barrel 9 for holding the projectile 10 from being discharged from the barrel until such time as the detent means is operated to release the projectile. Said detent means comprises preferably a pivoted detent member 27 which is pivoted to the barrel 9 by a transverse pin 28, the barrel having a longitudinal slot 29, into which the detent member 27 may pass when released.

For holding the detent member 27 in the inwardly and outwardly extending position shown in Fig. 7, there is provided a bell crank lever, one arm 30 of which is adapted to be swung against the outer side of the detent member 27 so as to force the latter to the holding position shown in Figs. 2 and 7.

The bell crank lever is pivoted at its angle 31 to the outer side of the barrel 9 and its other arm 32, Fig. 1 has pivoted to it one end of a longitudinal rod .33, the other end of which is pivoted to one arm 34 of a bell crank lever pivoted at its angle by a pin 35 to the outer side of the chamber 8. The other arm 36 of said bell crank lever is adapted to be struck and swung by a cam 37, Fig. 9, which is provided on the periphery of a sleeve 38 which is slidable longitudinally on a cylindrical bearing 39, Fig. 8, in which the shaft 2 is rotatably mounted. The sleeve 38 with its cam 37 is movable to and from a position in which the cam 37 will be in the path of movement of the arm 36 of the adjacent bell crank lever, thereby swinging said lever and its arm so as to release the detent member 27, through the intermediacy of the rod 33 and bell crank arms 32 and 30.

Fo returning the detent means to the holding position, there is provided a coil spring 40, Fig. 1, which is attached to the barrel 9 and to the rod 33 in a manner such as to normally force the rod 33 longitudinally outwardly.

When the sleeve 38 is forced against the chamber 8, so that the cam 37 is in the path of the bell crank lever arm 36, and the barrel is revolving with the shaft 2, the cam will swingsaid lever so as to release the detent member 27 once during each revolution of the barrel 9 on its axis.

In order that the point of contact or time of contact of the cam 37 with the arm 36 may be changed, so that the detent member 27 may be eleased at different angles of the barrel 9, the sleeve 38 is circumferentially adjustable within predetermined limits by neans of the following described mechanism. The sleeve 38 is provided with a radial arm 41 to which is pivoted one end of a horizontal bar 4 2, Fig. 10, the other end of which is pivoted to a vertical bar 43, which, intermediate of its ends, is pivoted by a pin 4% to the frame work 1. The lower end of the bar 13 is pivoted to the rear end of a forwardly extending rod 15, Fig. 1, the forward end of which is pivoted to the lower end of a lever 16, which is pivoted by a pin 47 to a piston frame 48.

The lever 4-6 is locked in the position to which it may be adjusted by an arcuate toothed plate 49 which is adapted to be engaged by a sliding bolt 50 connected by a rod 51 with a bell crank lever 52 pivoted to the lever 1-6 adjacent to the upper end thereof.

By throwing the lever 16 so as to draw the rod forwardly, the sleeve and cam 38 and 37 respectively are turned clockwise, as viewed in Fig. 1, so as to sooner have the cam engage the bell crank lever arm 36, thereby releasing the detent member 27 when the barrel 9 is at a greater angle to the hori zontal than when thelever -16 is swung in the opposite direction. I

If desired, such retraction of the lever 46 in the opposite direction may be efiected by a coil spring 53, Fig. 1, one end of which is secured to the frame 1 and the other end of which is secured'to the bar 43 above the pin 44.

Thus by swinging the lever 46 to different positions, the angle at which the gun is fired may be varied to suit the operator.

For moving the sleeve 38 longitudinally into andout of the operative position, I provide a vertical bar 54, which is pivoted intermediate of its ends by a horizontal pin to the frame 1. j

The lower end of the bar 54 is secured to one end of a coil spring 56, Fig. 4 and Fig. 6, the other end of which is secured to the frame 1 in a manner such that the spring 56 will normally swing the bar 54 so as to move the upper end of the said bar outwardly.

The upper end of the bar 54 is provided with two arms 57 respectively provided with inwardly extending pins 58 which are re spectively mounted in slots 59 provided in diametrically opposite sides of the sleeve 38.

In order that the upper end of the bar 54 may be swung inwardly, a horizontally disposed bell crank lever, which is pivoted by means of a vertical pin 60 to the. frame 1, has oneof its arms 61 mounted in a transverse hole provided therefor in the bar 54 adjacent to the lower end thereof, as shown in Figs. 4 and 6. The other arm 62 of said hell crank lever is attached to one end of a horizontal longitudinally disposed coil spring 63, 6, theforward end of which is attached to a longitudinally movable horizontal bar 64, the forward end of which is pivoted to the lower end of a lever 65, which is pivoted to the frame 48.

By throwing the upper end of the lever 65 rearwardly, that is toward the frame 1, the bar 64 is drawn forwardly and by means of the spring 63 and bell crank lever 62, will swing inwardly the upper end of the bar 54, thereby sliding the sleeve 38 to a position in which the cam 37 will be in the path of the bell crank lever arm 36, so that when said arm strikes the cam, the detent member 27 will be released and the projectile 10 held thereby will also be released and will be projected by centrifugal force from the barrel 9.

In order that the projectiles 10 may be fed one by one at the proper time from the magazine 13 into the chamber 8, I provide the following described escapement mechanism.

' Referring now particularly to Figs. 2 4, 6. 11 and 12, 66 designates a horizontalrock shaft which is pivotally mounted in two arms 67 of a metal loop which is vertically disposed and embraces and is secured to the two arms of the magazine 13. Pivotally mounted on the rock shaft 66 is a collar 68 provided with a crank 69 which is pivoted of which is pivoted to an arm 71 of a bell crank lever which is pivoted by a horizontal pin 72 to'the frame 1. The other arm 73 of the said lever is pivoted to the rear end of the bar 64.

Rigidly secured to the collar 68 is a crank 74 which is adapted to move from the released position, shown in solid lines in Fig. 11 througha slot 75 in the upper side of the lower arm of the magazine 13 to the position shown in dotted lines in said figure, in which latter position the crank 74 will hold the foremost projectile 10 from passing out of the magazine into the gun barrel chamber 8.

When the lever 65 has its upperend swung toward the frame 1, the bar 64 will be drawn forwardly, thereby rocking the collar 68 so that the crank 74 will be thrown to the holding position shown in dotted lines in Fig. 11.

Upon swinging the lever 65 in the opposite direction, the collar 68 will be rocked in the opposite direction to the position' shown in solid lines in Fig. 11, thereby releasing the foremost projectile 10 which will then enter the chamber 8 and will then pass, due to centrifugal force, into the barrel 9 and against the detent member 27 where it will be held until released by the operator again swinging the upper end of the lever 65 toward the frame 1. Upon such swinging of the lever 65, the detent member 27 will be released through the intermediacy of the cam 37, bell crank lever 3634, rod 33, and bell crank lever 323130, the cam sleeve 38 being moved to the operative position through the intermediacy of the bar 54, bell crank lever 6l62, spring 63 and bar 64.

At the same time, the sleeve 68 will be rocked so that the crank 74 will pass to the position shown by dotted lines in Fig. 11, through the intermediacy of the crank 69, bar 70 and bell crank lever 7 17 3.

In order that, when the foremost projectile 10 in the magazine is released by the movement of the crank 74 to the position shown in solid lines in Fig. 11, due to the forward swinging of the upper end of the lever 65, the next projectile 10, shown in solid lines in Fig. 1]., shall be held back, the rock shaft 66 is provided with a crank arm 76, which is adapted to pass from the position shown in dotted lines in Fig. 11 to the position shown in solid lines in said figure. In the latter position, the crank arm 7 6 will engage the projectile next to the foremost one and will hold it until the bar 7 0 is again moved downwardly due to the rearward swinging of the upper end of the lever 65.

The collar 68 is notched to receive the crank arm 76, so that the latter may have a slight circumferential movement with the rock shaft in the collar 68. A coil spring 77 encircling the rock shaft 66 and secured at one end to the loop 67 has its other end bearing against the crank arm 76 in a manner such that the latter will normally be held against a shoulder 78 on the collar 68. In case that the crank arm 76 should strike on top of a projectile 10, the spring 77 will yield while the collar 68 is being turned so as to raise the crank 74 to release the foremost projectile. As soon as the collar 68 is turned so as to depress the crank 74, after the foremost projectile has been released, the shoulder 78 of the collar 68 will strike the crank arm 76 and swing it upwardly through the slot 75, thereby releasing the next projectile, which will then roll downwardly until it is stopped by the crank 7 4.

The lever 65 may be pivoted, as is the lever 46, to the pin 47.

The barrel may; have secured to it a counter balance comprising two outwardly extending bars 79 secured to the periphery of the chamber 8 opposite to the barrel 9, and having secured to their outer. ends a weight 80.

For assisting in retracting the bell crank lever 717 3 and the parts connected therewith to the position shown in Fig. 2, a ver tical coil spring 81 may have one end secured to the lever arm 71 and its other end secured to the frame 1.

For limiting the swing of the lever 34-36 against the tension of the spring 40, a stop 82 may be provided on the outer side of the chamber 8.

For the purpose of preventing the projectiles pocketing in the chamber 8, and to insure their passing into the barrel 9, the inner periphery of the chamber 8 may be provided with a lining 83 which gradually increases in thickness each way from the barrel 9, the thickest portion being diametrically opposite the longitudinal center of the barrel 9. The inner wall of the chamber 8 is thus eccentric to the shaft or axis 2, with that portion which is most distant from the axis being nearest to the inner end of the barrel 9.

In order that the projectile may not be thrown too forcibly against the detent member 27, the inner wall of the barrel 9 is lined with yielding corrugated strips 84, the corrugations at opposite sides of the barrel being arranged so as to slightly shift laterally the projectile as it passes through the barrel. This changing of the course of the projectile, as well as the friction against the lining strips 84 will reduce the speed of the projectile as it passes through the barrel 9 to the detent member 27.

In operating my invention, the motor 3 is started, thereby rotating the barrel 9 in the direction indicated by the arrow in 1. The magazine 13 is then filled with projectiles. If the lever 65 is in the position shown in Fig. 1, the foremost projectile 10 will rest against the crank arm 76. If now the lever 65 is swung rearwardly at its upper end, the bar 64 will be forced forwardly, thus swinging downwardly the bell crank arm 71, and through the intermediacy of the rod 7 0 and crank 69 rocking the collar 68 to the position shown in dotted lines in Fig. 11, in which position the crank arm 74 will engage and hold the foremost ball or projectile 10, the latter having been released from the crank arm 76. If now the lever 65 be swun forwardly, or to the left, as viewed in Fig. 1, the collar 68 will be rocked in the opposite direction from that in which it was first rocked, thereby depressing the crank arm 76 and lifting the crank arm 74 so as to release the foremost ball or projectile, upon which the latter will roll by gravity into the chamber 8 from which it will pass, due to centrifugal force, into the barrel 9 and against the detent member 27, where it will remain until the detent member is released from the arm 32. The gun will now be in condition to be fired. The operator will now swing the lever 46 so as to adjust the cam 37 to the proper position circumferentially for the angle at which the gun is to be discharged.

If now the lever 65 be swung at its upper end to the right, as viewed in Fig. 1, the cam 37 will be forced into the path of the lever arm 36, through the intermediacy of the bar 64, spring 63, bell crank lever 62-61, bar 54 and sleeve 38, so that when the barrel 9 has revolved to the proper position, the detent member 27 will be released by the mechanism already described, and the projectile which has been carried in the barrel will be discharged by centrifugal force.

When the lever is swung to the right, as above described, the collar 68 will be rocked so as to swing upwardly the crank arm 76 and downwardly the crank arm 74, thus permitting the projectile which is now foremost in the magazine to roll downwardly against the arm 74. 7 Upon then swinging the upper end of the lever 65 to the left, as viewed in Fig. 1, the collar 68 will be rocked so as to lift the arm 74, thereby releasing therefrom the foremost projectile, which willnow roll into the chamber 8 and into the barrel 9, where the projectile will be held by the detent member 27, the latter having been restored to the holding position by the last swinging movement of the lever. The gun will now be loaded so as to be again fired at the will of the operator in the manner already described.

The projectiles which have been fired if falling or thrown upon the inclined ground 17, will roll into the inclined chute 16 and will pass therein one by one to the conveyer where they will be picked up one by one by the blades 15 and discharged thereby into the upper end of the magazine 13. If there are more projectiles than the magazine will hold, the surplus ones will be discharged laterally from the semicircular plate 18.

As the range of movement of the bar 64 is greater than is required for the bar 54 in swinging the sleeve 38 to the operative position, the spring 63 is inserted between the bar 6% and the lever arm 62. The spring 63 is stronger than the spring 56 so as to permit it to overcome the latter when the bar 64: moves forwardly.

In Fig. 3 is shown a modified form of barrel designed to reduce the speed of the pro ectile as it moves outwardly in the barrel 85, which is of involute form, :and which at its outer end is provided with a radial cylindrical tubular portion 86, in which are mounted a detent member 27 and a bell crank lever 30 similar in .form, mode of operation and function to the like designated elements in the other form ofmy invention.

In the form of my invention shown in Fig. 3, the shaft 2 to which it is secured is disposed substantially centrally, and the pro ectiles are fed into the barrel closely adjacent to the shaft 2. As the barrel 85 revolves, the projectiles will be caused by centrifugal force to travel outwardly through the involute barrel until they reach the detent member 27, where they will rest until this member "is released by mechanism already described with reference to my other form of invention. The open side of the involute barrel 85 will be normally closed by a plate corresponding to the plate 11 having the opening 12 communicating with the magazine 13.
